Hi
Thanks for using FixYa. As the sound is working fine then the issue seems to be with a bad inverter board and/or it is the not getting the required power supply (20vdc) from the power supply board of the unit. To resolve this issue you'll have to open the unit and check the inverter board which is the power supply source for the backlights. If that's the issue then it's always better to replace the inverter board completely just to avoid any future issues. Please accept the solution if the issue is resolved or post a comment for further assistance.
Thanks

It sounds like it could be a tuner, but not necessarily. Does it work on any inputs, such as DVD or any other devices you have hooked up? I would guess it does not, but please confirm.
Thanks

No.
Sound works, but screen black.
What would replacing the inverter cost?
Is it worth it given the price drops in the market?
Thanks,
Rick
